Suicidal attempt and psychiatric disorders in Iran

This study is part of broader research aimed to determine the lifetime prevalence and pattern of comorbidity on self-reported suicidal attempts in the general population of Iran. Overall, 25,180 subjects were interviewed, face-to-face, at home; the lifetime prevalence was 1.4% (0.9% males and 2% females). The majority of attempters were 26-55 years of age, married, more highly educated, female, retired, and lived in urban areas. Many of the attempters (45.3%) reported at least one psychiatric disorder during their lifetime; major depressive disorder (22%), panic disorder (6.3%), and obsessive compulsive disorder (6%) was the most common. Because less than half of suicidal attempters reported a psychiatric disorder, the existence of other pathways to suicide may be important foci for prevention. Many of the demographic correlates of suicidal behavior in Iran are very similar to those seen in Western cutlures; however, the sociodemographic factors such as few working women and very low levels of divorce is quite different to that of Western populations.     

Now you feel it, now you don't: frontal brain electrical asymmetry and individual differences in emotion regulation

Recent theoretical accounts of emotion regulation assign an important role in this process to the prefrontal cortex, yet there is little relevant data available to support this hypothesis. The current study assessed the relation between individual differences in asymmetric prefrontal activation and an objective measure of uninstructed emotion regulation. Forty-seven participants 57 to 60 years old viewed emotionally arousing and neutral visual stimuli while eyeblink startle data were collected. Startle probes were also presented after picture presentation to capture the persistence or attenuation of affect following the offset of an emotional stimulus. Subjects with greater relative left-sided anterior activation in scalp-recorded brain electrical signals displayed attenuated startle magnitude after the offset of negative stimuli. This relation between resting frontal activation and recovery following an aversive event supports the idea of a frontally mediated mechanism involved in one form of automatic emotion regulation.     

Post-traumatic stress disorder symptoms of children following the occurrence of Tehran City Park disaster

The authors investigated the post-traumatic stress disorder (PTSD) symptoms of young adolescents who had been directly involved in a disaster in Tehran. The participants were 19 chlidren who had survived a boat sinking in Tehran's city park in 2002. By using the Post-Traumatic Stress Disorder Symptom Scale (PSS; E. B. Foa, D. S. Riggs, C. V. Dancu, & B. O. Rothbaum, 1993) as well as a clinical interview based on the definition cited in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV; American Psychiatric Association, 1994, p. 424), 16 participants (84.2%) were diagnosed with PTSD using the PSS and 17 (89.5%) were diagnosed with PTSD using the psychiatric interview.     

Effectiveness of cognitive behavioral therapy on the signs,symptoms and clinical consequences of premature ejaculation

The purpose of this research was to assess the effectiveness of cognitive behavioral therapy (CBT) on the signs, symptoms, and clinical‐sexual consequences of premature ejaculation, including sexual esteem, sexual anxiety, sexual depression, sexual fear, and sexual satisfaction of patients and their wives. Fifteen patients with premature ejaculation were selected and received cognitive behavioral therapy of eight to 12 sessions. Finally, the data collected from 12 patients were analyzed using paired t‐tests. The results of the analysis showed that all of the variables changed after the treatment. All of the changes were statistically significant with a tendency towards improvement. CBT can be a more popular and effective treatment provided to patients suffering from premature ejaculation.     

The role of pain behaviour and family caregiver responses in the link between pain catastrophising and pain intensity: A moderated mediation model

Objectives: This study investigated the mediating role of pain behaviours in the association between pain catastrophising and pain intensity and explored the moderating role of family caregivers’ responses to pain in the link between pain behaviours and pain intensity.

Methods: The sample consisted of 154 chronic pain patients and their family caregivers. Patients completed questionnaires regarding pain intensity, pain catastrophising, pain behaviours and their caregivers’ responses to their pain. Family caregivers reported their responses to the patients’ pain.

Results: Pain catastrophising was associated with pain intensity (r = 0.37) and pain behaviours partly mediated this association. The positive association between pain behaviours and pain intensity was significant only if patients reported that their family caregivers showed high levels of solicitous (effect = .49) and distracting responses (effect = .58), and if caregivers reported to show high levels of solicitous responses (effect = .51). No support was found for negative responses as a moderator neither based on patients’ perception of negative responses nor based on caregivers’ perception of negative responses.

Conclusions: The findings are in line with the idea that family caregivers’ solicitous and distracting responses convey to patients that their condition is serious, which may reinforce patients’ pain and pain behaviours, especially in those who catastrophise.     

Sensitivity to the prototype in children with high-functioning autism spectrum disorder: An example of Bayesian cognitive psychometrics

We present a case study of hierarchical Bayesian explanatory cognitive psychometrics, examining information processing characteristics of individuals with high-functioning autism spectrum disorder (HFASD). On the basis of previously published data, we compare the classification behavior of a group of children with HFASD with that of typically developing (TD) controls using a computational model of categorization. The parameters in the model reflect characteristics of information processing that are theoretically related to HFASD. Because we expect individual differences in the model’s parameters, as well as differences between HFASD and TD children, we use a hierarchical explanatory approach. A first analysis suggests that children with HFASD are less sensitive to the prototype. A second analysis, involving a mixture component, reveals that the computational model is not appropriate for a subgroup of participants, which implies parameter estimates are not informative for these children. Focusing only on the children for whom the prototype model is appropriate, no clear difference in sensitivity between HFASD and TD children is inferred.     

Effects of action planning and coping planning within the theory of planned behaviour: A physical activity study of patients undergoing haemodialysis

Objective

Patients on dialysis have low physical activity levels. The aim of the study was to examine the validity of action planning and coping planning within the theory of planned behaviour framework, for predicting physical activity behaviour of patients on haemodialysis.

Design

This is a prospective study design.

Methods

One hundred and forty-four patients who were undergoing haemodialysis were selected from dialysis centres. The mean age of the patients was 56.61 (SD = 11.38) years. The patients completed a questionnaire including variables from the theory of planned behaviour, action planning and coping planning. Physical activity was prospectively assessed at 4-weeks with the validated International Physical Activity Questionnaire self-report measure. A hierarchical regression analysis was performed to examine the effects of action planning and coping planning on physical activity behaviour.

Results

There was a main effect for coping planning but not for action planning. Moreover, the analyses resulted in a significant amount of incremental variance accounted for by the interaction of coping planning and intention.

Conclusion

Results suggest the combination of high levels of coping planning and intention is associated with increases in physical activity.

Timing of HIV Interventions on Reductions in Sexual Risk Among Adolescents

Examined the effectiveness of an HIV intervention program among 151 adolescents ages 13 to 24 years who were randomly assigned to (a) seven sessions of 1.5 hr each (10.5 hr); (b) three sessions of 3.5 hr each (10.5 hr); or (c) a no-intervention condition. Using cognitive-behavioral intervention strategies, social skills and HIV-related beliefs, perceptions, and norms were targeted in both the three- and seven-session, small-group intervention conditions. Regression analysis indicated that over 3 months, the number of unprotected risk acts and the number of sexual partners were lower in the seven-session condition compared to the other conditions. Factors mediating risk acts changed in a complex manner: For example, perceived vulnerability increased for those with initially lower vulnerability scores among youths in the seven-session condition compared to others. Self-approval of condom use was also higher for those with initially low scores in the seven-session compared to the three-session condition. Self-efficacy for risk avoidance and condom use was significantly higher in the three-session condition for those with initially low scores compared to other groups. On the role-play measure, those with higher baseline scores in the low-pressure situation improved significantly only in the three-session intervention; in the high-pressure situation, the participants reported significantly higher scores in the seven-session intervention, and those with higher scores improved the most. Results suggest the importance of multisession HIV intervention programs to be delivered with fidelity in community settings.
